Abstract
The utility model discloses a heavy-current high-speed on/off controller which relates to a control device. The heavy-current high-speed on/off controller comprises a cabinet body, a vacuum circuit breaker, a low-voltage signal control cabinet, a fuse protector, a quick isolator, an electronic controller, an isolating transformer and a bus chamber, wherein the vacuum circuit breaker is arranged in the cabinet body and connected with the quick isolator, the electronic controller and the isolating transformer are connected below the quick isolator in sequence, the fuse protector is arranged at the front end of the quick isolator, and the upper end of the quick isolator is connected with the bus chamber. The heavy-current high-speed on/off controller adopts a microcomputer for monitoring, has high on/off speed and heavy on/off current, greatly reduces the investment of system expansion and networking, reduces the power consumption, saves electric energy, and reduces the damage to the equipment, the power grid and the motor caused by short-circuit impulse current.
Description
Technical field:
The utility model relates to a kind of control device, relates in particular to a kind of big electric current high-speed breaking control device.
Background technology:
Increase along with the generator unit capacity, the expansion of distribution capacity and each big electrical network interconnected, the short-circuit current value of distribution bus formula high-rating generator outlet also will improve thereupon, can be up to arriving 100KA-200KA, and traditional breaker open operation time generally is about 60ms～600ms, whole process is cut-off needs 100ms-200ms at least, and the peak value of fault current often appears at first half-wave, and the peak value of short circuit current can reach 3-4 the order of magnitude of rated current, serious tens orders of magnitude that can reach rated current.Because the contradiction that exists rated current and short circuit current to differ greatly reaches the restriction of material, structure, manufacturing, certainly will cause circuit breaker reliably not cut-off, thereby accident is enlarged.At the problems referred to above, the system that has selects for use current limiting reactor to suppress short circuit current, prevent to damage generating set, but because the power consumption and the electric power of current limiting reactor self, also reduced simultaneously the generated output of generator in operate as normal, make a part of electric energy become reactive power and waste, also increased the investment of equipment simultaneously.Traditional circuit breaker mainly exists the speed of cut-offfing slow, and drop-out current is little, the problem that foundation of investment construction project floor space is big.
The utility model content:
The purpose of this utility model provides a kind of big electric current high-speed breaking control device, it adopts micro computer monitoring, cut-off the speed height, drop-out current is big, significantly reduced the required investment of system's enlarging networking operation, reduce power consumption, save electric energy, reduce of the harm of short-circuit impact electric current equipment and electrical network, motor.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it is made up of cabinet, vacuum circuit-breaker, low-voltage signal control cubicle, fuse, quick isolator, electronic controller, isolating transformer and bus-bar room, be provided with vacuum circuit-breaker in the cabinet, vacuum circuit-breaker links to each other with quick isolator, the isolator below is connected with electronic controller and isolating transformer in turn fast, the isolator front end is provided with fuse fast, and the isolator upper end links to each other with bus-bar room fast.
The utility model adopts micro computer monitoring, cut-offs the speed height, and drop-out current has significantly reduced the required investment of system's enlarging networking operation greatly, reduce the Power Cutback electric energy, reduce of the harm of short-circuit impact electric current, and it is rational in infrastructure equipment and electrical network, motor, floor space is little, and installation and maintenance are simple.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
With reference to Fig. 1, this embodiment is by the following technical solutions: it is by cabinet 1, vacuum circuit-breaker 2, low-voltage signal control cubicle 3, fuse 4, isolator 5, electronic controller 6, isolating transformer 7 and bus-bar room 8 are formed fast, be provided with vacuum circuit-breaker 2 in the cabinet 1, vacuum circuit-breaker 2 links to each other with quick isolator 4, isolator 4 belows are connected with electronic controller 6 and isolating transformer 7 in turn fast, isolator 4 front ends are provided with fuse 5 fast, and isolator 4 upper ends link to each other with bus-bar room 8 fast.
This embodiment adopts micro computer monitoring, cut-offs the speed height, and drop-out current has significantly reduced the required investment of system's enlarging networking operation greatly, reduces the Power Cutback electric energy, reduces the harm of short-circuit impact electric current to equipment and electrical network, motor.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
